Title: The manufacture and production of soluble condensation products
IPC: C14C3/20
Filed: 1920-10-11
Abstract: Naphthalene, anthracene, phenanthrene, or other hydrocarbon at least bicyclic, or carbazole, or a halogen or sulphonic acid substitution product, is condensed with a carbohydrate, such as cellulose, starch, or their conversion products down to glucose, or with other sugars, in such a way that sulphonic acid groups are contained in the final product; that is to say, sulphonic acid is used as a condensing agent when a sulphonic acid is not employed as a reaction material. According to the example, naphthalene is condensed with cellulose in the presence of concentrated sulphuric acid; the product is neutralized with lime, filtered, the soluble calcium salt decomposed with sodium carbonate, and the filtrate evaporated to dryness.  The resulting soluble compound can be used as a tanning agent, or for the production of lakes from basic dyestuffs, particularly in the presence of metallic salts such as aluminium sulphate.  The Provisional Specification states that any derivative, except hydroxy derivatives, of the above-mentioned hydrocarbons may be used.

Filed: 1924-12-01
Abstract: 234,384. Tilton, H. B., and Morley Button Manufacturing Co. Dec. 1, 1924. Moulding golf tees.-Relates to a golf tee having a shank for insertion into the ground and a head for supporting the ball, and consists in forming the head of a fibrous material in which the fibres extend in different horizontal directions thereby preventing splitting. The shank 8 is cut from a sheet material such as hard vulcanized fibre-board, horn fibre or vulcanized paper, and is held between dies 11, while the head 9 is pressed in position by a plunger die 14. The pressing operation forms flanges 20, 22 on the shank above and below the head 9, and compresses the head into cup form. A flange 23 may be formed on the shank to determine the distance to which the shank shall enter the ground. When the heads are formed of a relatively soft material such as button-board they may be toughened and hardened after attachment to the shanks. The tees are finally painted.

Abstract: 791,620. Hydraulic jacks; fluid-pressure servomotor-control systems. BRITISH MESSIER, Ltd. Sept. 30, 1955 [Oct. 7, 1954], No. 28952/54. Classes 69 (2) and 135. [Also in Group XXVIII] An hydraulic jack for controlling an allmoving aircraft tailplane has screw means associated with the jack piston which are braked in order to lock the piston in any assumed position relative to its cylinder, and is provided with means for progressively decreasing the braking on application of pressure to the jack. A jack piston 18 is secured to the airframe and a jack cylinder 15 is provided in a casing 11 pivotally connected to the tailplane 13. A rotatable rod 27 having a screw connection with the piston is formed with a head 30 forming one part of a friction clutch, the other part 31 of which is non-rotatable and is urged into engagement with the head 30 by a spring 38, being disengaged by fluid pressure acting on the annular face of a piston 37 disposed in a clutch control cylinder 36. On manually moving a distributing valve 44 to either side of the neutral position shown, liquid is supplied from an inlet 67 to one side or the other of the jack piston 18, and also, through a duct 65 to the clutch control cylinder 36 to act on the piston 37. A bleed passage 39 passes from the left-hand chamber of the cylinder 36, through the piston to the right-hand chamber which is connected to exhaust through a fixed restriction 81. The left-hand chamber is also connected through a fixed restriction 85 to a port 82 of a clutch control valve 70, and thence around a reduced part of the valve to an exhaust duct 78. As pressure builds up on either side of the jack piston 18 it acts through a duct 76 or 77 on an extension 74 or a land 72 of the valve 70 and moves it to the right against the pressure of a spring 71. Port 82 is thus gradually closed and pressure builds up in the clutch control cylinder 36 to disengage the clutch. The housing of valve 44 is provided in the moving casing 11 thus producing a follow-up action for re-centring the valve.

A liquid fuel vaporizer comprises a trough 10 supplied with fuel and extending along a first vaporizing chamber 11 enclosing an electric heating element within a sheath 12 and a second vaporizing chamber formed by a helical wall 13. The vapour passes from the first chamber 11 to the second chamber through holes 15 in the helical wall 13 and from the second chamber to a nozzle orifice 17 directing the vapour into a Venturi mixing tube 22 leading to a burner gauge 25. The liquid fuel is supplied through a filter, a solenoid valve, and a manually-operated needle valve 7 to a small trough 8 and through apertures 9 to the first trough 10. The solenoid valve is operated by a thermostat 3 fixed in heat conductive relationship with the electric heater. When the temperature of the vaporizer drops below 450‹ F. the solenoid value is either closed or restricts the fuel flow. A pricker 17a for cleaning the vapour discharge orifice 17 is mounted on a C-shaped bi-metal strip so that when the temperature of the electric heater reaches a pre-determined value, the pricker is withdrawn from the orifice. The vapour is ignited by a gas pilot flame 26 which heats a bi-metal member 30 connected by a rod 31 to a microswitch 33. The latter energizes the electric heater when the gas flame has been in operation for a time. A second thermostat 34 extends into the vaporizing chamber 11 and cut-out or restricts the output of the electric heater if the temperature of the chamber rises to 550‹ F. Specifications 848,203 and 858,876 also are referred to.

The sound of a bell i imitated by simultaneous ly striking two rods 33 34 secured in a base 30 mounted on resilien supports 31. The base 30 also carries a bar 38 to which are attached two electrostatic pick-ups 4 (one for each rod 33, 34 feeding an amplifier an( loudspeaker (not shown) Each pick-up collecto plate 42 presents a com paratively wide face t( its corresponding rod and a narrow edge to the other rod, from which i is shielded by a meta plate 43. The two rod 33, 34 are tuned to dif ferent characteristic notes a minor third apart, but the pick-up on the lower-tuned rod is situ ated at a node of it fourth partial which nor mally interferes with the fifth partial to produce the characteristic note. The fourth partial and the original characteristic note are thereby suppressed, and the new characteristic note of the rod is in unison with that of the other rod, Figs. 3, 4 (not shown). The two rods together now provide the notes required for the sound of a bell, unwanted partials being removed by attenuation in the amplifier system. The vibration of the rods may be modified by movable weights 68 and restricted by springs 39 mounted on " stabilizers " 36. At the free. end of each rod there may be fitted a damping device adapted to act intermittently during the vibrations. This takes the form of a ball 35B resting in a sleeve 35C, Fig. 15, or of some other loosely attached member or a powdered material, Figs. 17-20 (not shown). A plurality of pairs of rods 33, 34, each pair having an electromagneticallyoperated striker and a base block 30, may be mounted in a frame, Fig. 7 (not shown), to form a carillon. The intermittently-acting damping device forms the subject-matter of divided Specification 684,666.

Title: Machine for automatically punching spinnerets
IPC: B21D31/02
Filed: 1956-09-25
Abstract: 800,928. Making spinnerets; punching. SOC. CHIMIOTEX. Sept. 25, 1956 [Oct. 13. 1955], No. 29302/56. Classes 83 (2) and 83 (4). In a punching machine for automatically punching holes in a spinneret, the punch is mechanically actuated through its working stroke and is withdrawn magnetically. The spinneret is held on a soft metal plate in a rotary work-holder 25 mounted on a table 26 sliding on a base 2. A frame 16 adjustable vertically by a hand wheel 19 is slidably carried by fixed posts 17 and supports the crankshaft 50 and a reciprocating ram 1 driven by the crankshaft 50. The punch 8 is secured to a support 9 attached by a rod 7 to a soft iron disc 10, and the rod 7 is slidable within a sleeve 5 secured in a bracket 3 attached to the ram 1. A permanent magnet 11 coacting with soft iron disc 10 to rase the punch 8 is supported on a bracket pivotally attached to the frame 16 so that the magnet 11 can be swung clear. The punch 8 is forced downwardly by contact of the bracket 3 with the support 9. Should the punch break, a feeler 27, Fig. 7, allows contacts 29 to open and stop the machine. The work-holder 25 is indexed each time the punch is raised by an eccentric 50 on the crankshaft which through a flexible cable 49 operates a pawl and ratchet drive 43. The stroke of the pawl is determined by engagement of an arm 53 rocked with the pawl with adjustable abutments 54 on a rotatable disc 55. A pattern 60 rotated with the work-holder 25 carries projections which when a portion of the spinneret to remain blank is beneath the punch operates a contact 62 to de-clutch the drive from the crankshaft and to start a motor 65 to rotate rapidly the work-holder 25. When the spinneret has been rotated through a complete revolution a projection 70 on the pattern holder operates contacts 72 to de-clutch the drive and to start a motor 73 which through an eccentric 74 and flexible cable 75 actuates a pawl and ratchet drive 80 and a step-by-step mechanism 90. The former rotates a threaded rod to move the table 26 and the latter steps the disc 55 to position a different abutment 54 adjacent the arm 53. When the pawl and ratchet device completes its stroke the drive is clutched to the crankshaft and the machine punches a circle of holes on a different radius, the angular spacing having been adjusted by the disc 55 so that the spacing between the holes is the same as that between the holes of the first circle. When a projection on the table 26 strikes a limit switch or alternatively when a counter operates a switch after a predetermined number of holes have been punched the machine is stopped. The machine is re-set manually.

Abstract: 1,274,916. Dispensing closures. ATLANTIC DESIGN & DEVELOPMENT CORP. 10 June, 1969 [10 June, 1968; 16 Sept., 1968], No. 29393/69. Heading B8T. A plastics dispensing closure assembly (10), Fig. 1 (not shown), comprises a closure member 11 which is pivotable between the solid and broken lines shown, by the application of finger pressure to the forward and rearward portions thereof respectively. An entrance port 32 in the member 11, through which the contents of container 36 pass, is connected to an exit port 31 through a substantially cylindrical passage 30 and aligns with an opening 34 in the closure assembly when in the open position (shown in broken lines). In its closed position the surface 27 seals the opening 34, on annular bead 35, providing a leakproof seal between the opening 34 and surface 27 while a similar seal is provided between the closure assembly (10) and container 36 by the annular bead 39. Because of the elasticity of the plastics material the application of finger pressure to the rearward portion of closure member 11 causes the depending skirt 44 to disengage from the wall portion 45 and pivot about the shaft 20 into its open position. The assembly may be secured to the container 36 by means of screw threads 37 or alternatively by means of an inwardly protruding annular rib engaging with an annular rib on the container neck, Fig. 6 (not shown). In a modification, Figs. 6-8 (not shown), which is particularly adapted for continuous pouring of liquids an air vent (74) is provided in the pivotal closure member. In a further modification, Figs. 9-12 (not shown), a dispensing container (110) for use with particulate matter has a pivoting cover (122) with spaced toothlike projections (130) projecting into an opening (118) in the container (110). When in the open position of the cover (122) the teeth are not completely withdrawn from the opening, thus providing a sieve like passage through which the particulate matter is dispensed.
